摘要


傳統無牙患者的治療計畫是全口活動義齒,相較於固定式植體支持的補綴物,費用較低廉,但是往往都有固持性、穩定性不足以及齒槽骨持續吸收,導致患者在配戴時會有諸多抱怨。尤其是在壓力承載區較小的下顎,而植體固持式活動義齒之贗復方式對恢復嚴重齒槽骨萎縮患者的咀嚼及發音等功能較傳統活動義齒有顯著的幫助,且能維持齒槽骨高度,使其吸收減緩。本報告為64歲男性接受上下顎植體固持覆蓋性義齒之臨床症例。

One of the common prosthetic treatment options for edentulous patients is the fabrication of complete dentures. Complete dentures cost less compared to other treatment modalities such as implant-supported fixed prosthesis. However, the lack of retention and stability that often associated with complete dentures results in complaints from the patients. One other major problem with complete dentures is the continuous resorption of the residual ridge. These shortcomings of complete dentures are especially prominent in the mandible, where the stress-bearing area is much smaller compared to that of the maxilla. On the other hand, implant-retained overdentures are helpful in restoring the masticatory and phonetic functions in patients with severely resorbed alveolar ridge. They are effective in maintaining the height of the residual ridge by slowing down the resorption process. This report presents a case of a 64-year old male receiving implant-retained overdentures in both the maxilla and the mandible.
